A

Explanation

Brood parasitism in birds is an example of parasitism in which the parasitics bird lays its eggs in the nest of its host and the host incubates them. This way, the bird can save the energy that it would have spent in incubation and can use that energy if foraging and other activities. During the course of evolution, the eggs of the parasite bird have evolved to resemble the host's eggd in size and colour to reduce the chances of the host bird detecing the foreign eggs and removing them from the nest. Laying eggs by cuckoo (koel) in crow's nest is brood parasitism. Cowbirds also show brood parasitism.
